Mohamed Al Fayed, the Fulham chairman, has called on the Premier League to explain its refereeing processes after accusing officials from England's top division of being "too easily influenced by the more powerful clubs and individual owners".

Fayed has become convinced that the bigger clubs, predominantly Manchester United and Chelsea, are getting unfair help and has demanded the Premier League – an organisation which, he says, is "in a coma" – to let the public know "the transparency of the processes by which referees are allocated to games".

He has now written a strongly worded letter to the League, as well as the Football Association, in which he demands an immediate review of the refereeing system.

"Referees are all too easily influenced by the more powerful clubs and individual owners and [it] calls into question the integrity of both them, and the governing body that they report to," Fayed claimed.

"The FA's problem in addressing this pivotal situation is that it has too much power. Where else can decision-makers escape all responsibility to admit serious and blatant errors and have the protesters [the clubs] fined on charges of misconduct?"

Ironically, Fayed may find he has talked himself into trouble by questioning the integrity of match officials, one of the key issues when the FA's disciplinary department decides whether it needs to take action.

He insists, however, there is strong evidence to back his argument that the smaller clubs get a raw deal, and he wants to know the system that is in place to decide who chooses the officials for each match. He is writing to the authorities, he says, on behalf of all the clubs involved.

It comes after a weekend notable for several contentious decisions that could have significant repercussions at both ends of the table, most notably when Chelsea scored two offside goals to beat Wigan Athletic 2-1 and Manchester United were helped to a 2-0 win over Queens Park Rangers by an early penalty that saw Shaun Derry sent off. Replays showed Ashley Young had dived but the FA have rejected QPR's appeal.

Fulham were the victim of another poor decision when they played at Old Trafford on 26 March, losing 1-0 after the referee Michael Oliver, the youngest referee in the top division, decided not to award a last-minute penalty for Michael Carrick's trip of Danny Murphy.

"The losses that we incur from such careless decisions have a huge impact and can have calamitous consequences," Fayed said.

He continued: "In the past I wrote to highlight the need for the Premier League to lead the way with the introduction of video technology. After many years, it appears that the Premier League has admitted I was correct all along.

"It is time for the Premier League to wake up. They have been in a coma for a long time. Lots of clubs are suffering from such stupid decisions.

Advanced technology is available and it is evidently being used in other sports.

"Once again I call for action to review the standard of officials, and the transparency of the processes by which referees are allocated to games."
